Specification of Letters Patent.

Patented Feb. 15, 1921.

Application led April 24, 1919. Serial No. 292,493.

To all whom it may concern:

Be it known that I, OTTO S. MARCKWORTH, a citizen ofthe United States, residing at Columbus in the county of Franklin and State of hio, have invented new and useful Improvements in Laminated Articles, of which the following is a specification.

This invention is a laminated article of manufacture of the type of the so-called non-shatterable glass.

One of the objects of the invention is to provide a covering for table and desk tops, wall panelings, tollets, and the like, capable of replacing marble, or the thick, brittle white glass plates which are now in vogue. A further object is to provide a laminated article of the character mentioned in which ornamental elements may be embedded. A further object is to provide a laminated article in which specimens of any character, photographs, documents and the like, may be embedded for preservation, display or advertising purposes.

The invention will be hereinafter fully set .forth and particularly pointed out in the claims.

In the accompanying drawing:

Figure 1 is a plan view illustrating a nonshatterable glass member with a piece' of lace embedded therein. Fig. 2 is a cross sectional view thereof. Fig. 3 is a plan view illustrating a non-shatterable glass member with a written document embedded therein for preservation. Fig. 4 is a similar view illustrating the method of embedding specimens for display and rotection. Fig. 5 is a sectional view thereof).

Referring to Fig. 1 of the drawing, 10 designates a body of non-shatterable glass, constructed of two laminas 11 of ordinary glass, united by a non-shatterable element 12, and having embedded therein an ornamental article such as a piece of lace 13.

The laminas may be united in any well known manner conforming to the practice of manufacturing non-shatterable glass, but it is preferred to follow the method disclosed in the copending application filed March 26th, 1919, Serial #285,348. AS pointed out in the said copending application an excellent non-shatterable glass 1s provided by uniting layers of glass and celluloid after they have been immersed in a celluloid solvent which is normally inactive but which is rendered active for a suiiicient period to produce the desired binding effect wlthout injury to the Celluloid. The specific solvent disclosed .in the said copending applicatlon for patent consists of propyl, butyl, or amyl alcohol or their mixtures, combined with camphor and most any one of the essential oils, especially oil of citronella, oil of cloves, or methyl salicylate. In practlsing the present invention a plate 11 o f glass is immersed in the solvent solut1on, a sheet of celluloid 12 is then immersed on' top of the glass, then the piece of lace 13 is positioned, after which another sheet of celluloid is placed on top of the lace, and finally another piece of glass is placed in position. After the lamlnae have been removed from the bath, the excess of the solution is squeezed out from between the laminas, and the whole subjected to pressure at the proper temperature to secure the desired action of the solvent. The pressure applied is preferably at the rate of from fifty to four hundred pounds per square inch of surface, depending upon the character of the material.

The article illustrated in Fig. 3 is constructed in identically the same manner as the article illustrated in Fig. 1, but if the document is of a nature which needs to be protected from the action of light, the celluloid laminar may be selected from the standpoint of color or actinic-ray absorption, so as to protect it completely.

ln the forms illustrated in Figs. 4 and 5 the glass member 14 is molded with a cavity 15, to receive the specimen 16, the celluloid members 17 being provided with openings to accommodate the specimen, the weld taking place between the ianges 18 of the glass members 1li.

An article of manufacture such as herein described is susceptible of many variations and wide use, and no attempt has been made to illustrate all of the forms of the invention. For instance opaque sheets of colored Celluloid may be employed as the Celluloid 4laminas if an opaque glass is desired, or celluloid which has been lithographed or in any way dyed, or carrying designs of any character may be employed, and could frequently be handled in single sheet form. The invention is capable `of many other uses such as the preservation and mounting of photographs, for the making of permanent lantern slides and transparencies and other objects of a similar nature. A further advantage of the invention is that the solvent solution employed for uniting the lamina: has distinctly preservative and antiseptic qualities, and being neutral, non-corrosive and harmless in every way, it is adaptable for every conceivable purpose where the embedded article is to be preserved. Other forms of the invention may =be embodied in colored table tops, desk tops, wall panelings, toilets, etc., or in lieu of the material of solid color, tapestries, laces, linens, etc., may 'be-embedded between. the laminae, portions of the sheets of glass could be left transparent at will by interposinr'a lace article such as a doily, in the case of5 a dressing table, or of a piece of linen to represent. a table cloth or other table cover.

Having thus described the nature of the invention and explained an operative manner of constructing and using same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. A laminated article comprisingtransparent laminae of non-shattera'ble glass having embedded therein an article of foreign material.

2. A laminated article comprising transparent laminae of non-shatterable glass provided with an embedded display element visible through the glass.

3. A laminated article comprlsingtransarent lamm of non-shatterable glass .hav-

ing means for controlling the amount of light passing'therethrough, and provided wlth an embedded display element visi-bl through the glass.

4. A laminated article comprising glass 40 and a display element interposed between the celluloid laminae, said celluloid laminae being of a color to resist actinic eect of light.

6. A laminated article comprising glass laminas chambered to receive an article to be displayed, and celluloid laminae permanently uniting the glass laminae and inclosin said article.

A laminated article com-prisin laminae of glass and celluloid, an interpose solvent binder of a nature incapable of destroying the transparency of the celluloid under normal atmospheric conditions, and a display article embedded between said laminae.

In testimony whereof I have hereunto set my hand. o

OTTO S. MARCKWORTH.
